1985 Rx-7 GSL-SE restoration and SBC 283 swap

New member here. Bought this car roughly in 2007. It's a 1985 Rx-7 GSL-SE, bought it with no motor or transmission. Found grannysspeedshop.com and decided on a Chevy powerplant and standard transmission. Started rust repair and restoration in high school shop class but ended up getting getting put on the back burner due to not being able to find an affordable manual transmission. And lack of money to put into the project.

So about a year ago I ended up getting a Chevy T-5 from a buddy out of his 87 Camaro and found a pair of SBC's for cheap. One a 1967 283 and the other one a four bolt main 350. Finally got the car home and into my garage about a month ago and quickly got it mostly stripped down. Have decided on full restoration. All rust and damage will be getting properly repaired. Everything going back on the car will be new/painted/powedercoated.

Decided on using the 283 since it should be a slightly faster/higher revving engine. Will be doing a full build on the motor, looking to make anywhere between 3-400hp and hopefully rev out to about 7k. The T-5 is in working order but apparently did occasionally pop out of second gear. Will probably rebuild the transmission as well.

This will definitely not be a fast build since I haven't won the lottery yet lol but I will try to update often and hope you all like the build

Has been in a small accident before. Minor front end damage.

Very very dirty.

Getting ready to clean off many years of dirt and grime.



Almost ten years of sitting shows 😑

All cleaned up! Looking much better after a good wash.


Engine bay looking way better



Dirty interior. Definitely seen better days. Seats and door panels are definitely cooked

Disassembled the back half of the interior back in high school.

Love the Supra rim offset!

Starting disassembly

Lists for things needing to be done, Parts needed for car, and parts needed for powertrain/drivetrain.

Wiring is definitely one thing I'm dreading the most. 😖

Rear bumper off

Rear axle/suspension dropped

Front bumper and hood removed, and front suspension/steering/crossmember dropped
